Product information "ALLin™ Mega HiFi DNA Polymerase"

Derived from our HiFi polymerase, the highQu ALLin™ Mega HiFi DNA Polymerase provides much lower error rate PCR with a 100 higher fidelity compared to Taq. The ALLin™ Mega HiFi DNA Polymerase is engineered to be much faster and to generate a higher yield of long PCR products up to 20 kb from complex GC-rich templates. Therefore the ALLin™ Mega HiFi DNA Polymerase is an excellent choice for longer and very complex PCR applications where the highest fidelity is demanded. It is an enzyme of choice for cloning and all kind of sequencing applications including NGS. Generated blunt-ended PCR products are suitable for ligation into blunt vectors.
For maximum convenience, the ALLin™ Mega HiFi Mastermix, 2X (HLM0201) and ALLin™ Mega HiFi Red Mastermix, 2X (HLM0301) are available.

Pfu DNA Polymerase was originally found in thermophilic bacterium Pyrococcus furiosus. It is a thermostable DNA polymerase that was widely used in molecular biology applications for its high fidelity of DNA amplification due to a high proofreading activity. Pfu polymerase has 3' to 5' exonuclease proofreading activity, which enables it to correct errors that occur during DNA synthesis. The enzyme is commonly used for cloning and sequencing applications, however it is relatively slow, sensitive to contaminants and inhibitors and has low processivity resulting in usually low PCR yields.

Alternative, mostly better DNA polymerases have been developed by different companies to address the limitations of Pfu polymerase. These include such enzymes as Phusion® DNA polymerase, Q5® DNA polymerase from NEB, and many others. These enzymes offer improved elongation rates, reduced error rates, and increased efficiency for NGS applications.

The ALLin™ MEGA HiFi Polymerase offered by highQu provides 100X higher fidelity compared to Taq Polymerase, which is much higher than Pfu. In addition, the hot start enzyme version allows to reduce the background to the minimum. Such robust enzyme offers not only precise amplification, but also enables PCR from very complex templates and generation of very long PCR products up to 30 kb and above.

Availability of faster, more robust and more precise polymerases influenced successful development of next generation sequencing techniques (NGS) where PCR precision and yield is crucial for reliable sequencing results.

HighScriber™ Reverse Transcriptase Mix
The HighScriber™ Reverse Transcriptase Mix is a premium tool for the high efficiency reverse transcription of up to 12-15 kb long cDNA. Mix includes HighScriber™ Reverse Transcriptase and Ribonuclease Inhibitor for save, robust cDNA synthesis and ease of use. HighScriber™ Reverse Transcriptase allows for high detection sensitivity from 1 pg of total RNA. The wide reaction temperature range (38°C - 55°C) ensures efficient cDNA synthesis from complex or GC rich templates. The enzyme uses ssRNA or ssDNA as a template, possesses no detectable Ribonuclease H activity specific to RNA in RNA-DNA hybrids. A highly reduced Ribonuclease H activity allows for transcription of full lengths long transcripts. HighScriber™ Reverse Transcriptase can be used for RACE as it has terminal transferase activity - adds cytosines to 3’ ends of cDNA. The Ribonuclease inhibitor premixed with the RT ensures RNA protection from ribonuclease degradation. Supplied 5X ALLin™ HighScriber Buffer includes everything you need for the cDNA synthesis reaction. To minimize pipetting steps it contains MgCl2, dNTPs, enhancers, stabilizers. The only things to add is the template RNA and primer.

StainIN™ GREEN Nucleic Acid Stain
StainIN™ GREEN Nucleic Acid Stain is a significantly safer alternative to ethidium bromide. It is same easy to use, 4X as sensitive (under Blue LED) and much more secure. More economical as other green dyes, this stain can be also used and disposed with less environmental and health concerns compared to ethidium bromide. It is a fluorescent dye that allows detection of >0,1 ng of DNA in both agarose and polyacrylamide gels. It binds to both dsDNA, ssDNA and RNA and emits green fluorescence when bound to DNA and red fluorescence when bound to RNA detectable under the UV or Blue light and documented with same filters as similar green dyes. StainIN™ GREEN is ideal for DNA extraction from gels for cloning. Smaller than ethidium bromide carcinogenicity has been proved by Ames-test. Mammalian cell mutagenicity tests, both mouse marrow erythrocyte micronucleus and spermatocyte chromosomal aberration tests gave negative mutagenicity results. Carcinogenicity and toxicity of the widely used Ethidium Bromide (EtBr) is one of the biggest safety and environmental problems in the labs where gel electrophoresis is a daily routine. The less toxic nucleic acid dyes address this problem and minimize concerns. The StainIN™ GREEN (SYBR Green-like stains alternative), (SYBR® Green is a registered trade mark of Molecular Probes Inc.) and StainIN™ eco-RED Nucleic Acid Stains by highQu provide a much less-carcinogenic, significantly safer alternative to EtBr while delivering even several times higher detection sensitivity. Same like EtBr, these stains are used during the process of electrophoresis in an agarose gel or PAAG and in the electrophoresis running buffer. Nucleic acid stains are typically divided into two groups – they are either intercalating dyes or minor groove binders. The StainIN™ GREEN and StainIN™ eco-RED Nucleic Acid Stains belong to the group of intercalating dyes that bind to NA and produce the fluorescence signal. Same like many other suppliers of similar products, highQu retains the right to keep the precise chemical information undisclosed and proprietary. The StainIN™ GREEN Nucleic Acid Stain as well as the StainIN™ eco-RED Nucleic Acid Stain are both supplied in water. Detailed safety information is available in MSDS sheets of the stains. Despite proven less mutagenicity, all nucleic acid stains, including SYBR® Green or other shall be handled with care. Used electrophoresis buffer with a stain as well as melted gels shall be run through approved (carbon) filters. If the absence of residual fluorescence is confirmed, the liquids can be disposed with plenty of water down the drain. Alternatively, all used liquids can be autoclaved as the StainIN™ GREEN and StainIN™ eco-RED Nucleic Acid Stains degrade during the long exposure to above 100ºC temperature. The safety office shall be consulted periodically to match local regulations, as they vary and change.
